LONDON — Chelsea striker Diego Costa was banned for three matches Tuesday after a charge of violent conduct during his team's 2-0 win over Arsenal at Stamford Bridge was upheld by a disciplinary panel. Costa had denied an English Football Association charge over Saturday's incident, not seen by referee Mike Dean, in which he appeared to raise his hands to Gunners defender Laurent Koscielny. Earlier Tuesday, Arsenal defender Gabriel Paulista won an appeal against his red card for confronting Costa after the initial incident during the weekend's showcase match in the Premier League. — AP
